Living in RV but out of town over night so I have a little time.

Replaced transfer switch a few months ago after old one (recalled model) burned up. Everything has been peachy.

Just walked in and the EMS display is off. All outlets and appliances have power. Tsat has no power. No lights.

Ideas? Thanks!

If you have power at the receptacles at least part of the transfer switch is working. IF the A/C's work all of it is. That would have me looking at the wiring to the to the EMS.

Not sure what a Tsat is.

It's really a matter of following the wiring of what is not working.

Checking a few things like the microwave display is a clue. IF you have two A/C's and they both work then both legs of a 50 Amp service are working. That is a check for the transfer switch and distribution panel feed. If all that is working it sounds like an EMS issue that could be anything from a loose connector at the panel to a bad panel to something in the management switching part of the system. A little looking with a meter should point it out.

I had a similar problem, after several hours of searching I discovered it was the GFI in the bathroom had been tripped!

I would give Intellitec a call, other members of the forum have posted good results in talking to Intellitec.

Thermostat and lights are 12v DC. Converter went bad?

It sounds like a 12 volt issue to me.
Lights and thermostat and powered by 12 volt, I don't know for sure about the EMS display, but I presume it works when you're driving down the road, so it's probably 12 volt also.

Check the charge and connections on the house batteries.

Thanks all, this is a good start

another angle. Check house batteries if Converter or inverter what ever you have may have stopped charging the batteries. What happens when you start the generator or the coach engine. If it is the battery a cheap quick temporary fix is a battery charger form Harbor freight or Tractor supply.

If any of the A/C's are working the house 12 VDC is working. Ditto refrigerator. "All appliances have power" would indicate that.

The reason for checking both A/C's is that they are usually on different legs of the 50 Amp service.

Good point.
I'm assuming that since the Tstat ('thermostat' is the way I interpret that) has no power that the air conditioners aren't working simply because their controller has no power.
Whether or not the refrigerator will turn on is another good point to check.

I agree with this answer.

Another easy 12 VDC check is the lights. If they light you have 12 VDC. If they light with the shore cord unplugged and generator off then you have continuity through the storage relay and that part of the system.

There could be a blown 12 VDC fuse on one branch circuit.

Well I found the problem....

My BUTT. Apparently I hit the cut out switch by the door AGAIN.

I totally don't understand why it's where it is. But alas.

Thanks everyone!
